NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL EP192009
200 AM PDT WED OCT 14 2009
PATRICIA HAS BEEN DEVOID OF ORGANIZED DEEP CONVECTION SINCE AROUND
1800 UTC...AND IS THEREFORE BEING DECLARED A REMNANT LOW AT THIS
TIME. THE INITIAL INTENSITY IS LOWERED TO 25 KT BASED ON AN ASCAT
PASS AT 0504 UTC. REGENERATION IS NOT EXPECTED SINCE THE LOW WILL BE
MOVING INTO AN INCREASINGLY DRY AND STABLE ATMOSPHERIC ENVIRONMENT
AND OVER COOLER SEA SURFACE TEMPERATURES. HOWEVER...TRANSIENT
BURSTS OF CONVECTION ARE POSSIBLE UNTIL DISSIPATION.
THE INITIAL MOTION ESTIMATE IS TOWARD THE WEST-NORTHWEST...300/05. A
TURN TOWARD THE WEST IS EXPECTED LATER TODAY AS A LOW- TO MID-LEVEL
RIDGE BUILDS TO THE NORTH OF THE REMNANT LOW. THIS WESTWARD MOTION
IS EXPECTED TO CONTINUE UNTIL THE LOW DISSIPATES IN THE NEXT DAY OR
TWO.
THIS IS THE LAST ADVISORY ISSUED BY THE NATIONAL HURRICANE CENTER ON
PATRICIA. FOR ADDITIONAL INFORMATION ON THE REMNANT LOW PLEASE SEE
HIGH SEAS FORECASTS ISSUED BY THE NATIONAL WEATHER SERVICE...UNDER
AWIPS HEADER NFDHSFEPI AND WMO HEADER FZPN02 KWBC.
